Since Plesk Obsidian release some of client functions listed above may not function properly due to Plesk sending too strict CORS headers after SSO made from HostBill.
To solve this:
- login to your Plesk Obsidian installation using SSH
- Edit /usr/local/psa/admin/conf/panel.ini
- Append following lines:
sameOriginOnly = false
sameSiteCookie = "None"
trustedRedirectHosts = your.hostbill.domain
